The tar-rich coal is not only coal, but also a kind of coal-based oil and gas resources. If the pyrolysis technology and scale application are broken through, the abundant oil resource derived from tar-rich coal can be obtained. The underground in-situ pyrolysis technology of tar-rich coal has been proposed lately. Through this technology, the oil-gas resources with in tar-rich coal are preferentially extracted without environmental pollution and excessive semi-coke production. Here, the pyrolysis and mild oxidation characteristics of tar-rich coal were firstly evaluated using thermogravimetric analysis.
